| Car power | In tire terms it translates as traction. For example, in order to be able to exploit all the force of a powerful engine you need high adherence tires. If not, some of the power is lost through skidding and the tires wear out too quickly. |
| Safety | Depending on the car makers' specifications, tires are designed to carry a well-determined weight, endure a maximum speed and offer a minimum braking distance. |
| Comfort | It is influenced by the rigidity of the tire and the height of it's wall. Car makers recommend an optimal size. You can go for a larger wheel with slick tires in order to keep the same overall diameter. You will gain in traction and maneuverability but you will lose in comfort. |
| Maximum speed capability | All tires come from the manufacturer with a speed rating embossed on their walls. They are guaranteed only if that maximum speed limit is respected. If you fit a 270km/h car with T rated (190 km/h) tires, it's clear that you would not be able to use that car at full potential. |
| Load index | All tires have a load index embossed on them. It represents the maximum weight the tire can carry. If that limit is not respected, the tire deteriorates fast and becomes a possible danger while rolling. Of course, the guarantee is lost. |
| Looks | Looks are becoming more and more important for cars. The looks of a tire can totally change the perception of a car, both in the positive and the negative sense. |
